ROLLER-BEARING.

SPECIFICATION forming part of Letters :Patent No. 584,893, dated June22, 1897.

Application filed August 14, 1896.

T0 LLZZ whom t nca/,y concern,.-

Be it known that I, THOMAS J. REID, a citizen of the United States,residing at Washington Court-House, in the county of Fayette and Stateof Ohio, have inventeda certain new and useful Improvement inRoller-Bearings, of which the following is a specification.

My invention relates to antifrictional 4journal-bearings; and theobjects of my invention are to provide a combined ball and rollerbearing of such improved construction and arrangement of parts as toprovide a uniform wear of both balls and rollers, to provide means foradjustment of the rollers and balls, sleeves and casings, to reduce thefrictional contact between the rollers, to prevent undue lateralmovement of said rollers and consequent wear of the parts, and toproduce other improvements, the details of construction of which Will bemore fully pointed out hereinafter. These objects I accomplish in themanner illustrated in the accompanying drawings, in which- Figure 1 is acentral vertical section of a journal-box having myimprovements'therein. Fig. 2 is a transverse section on line x00 of Fig.l. Fig. 3 is a detail view showing two adjacent rollers and their endballs, said rollers being shown in longitudinal section and Fig. 4 is apartial longitudinal section of a j ournal-box, showing a modiliedconstruction and arrangement of the bearings.

Similar letters refer to similar parts throughout the several views.

d represents the box or external case, which is provided on its innerend with the inturned flange portion a. On the inner side of the box d Ifit an inner casing which, as indicated in the drawings, is formed ofseparated sections 01,2 a3, the inner surfaces of these sectionstapering toward their inner ends. The outer end of each of thesecasing-sections has a threaded connection with a cone-bearin g ring b.

c and c represent the axle-spindle sleevesections, which, as prescribedfor the inner casing-sections, are separated centrally and have theirouter surfaces inclined or tapered toward their inner ends. The innerend of the section c has a threaded connection with an innercone-bearing ring c2, which forms an inner end extension of thesleeve-section c.

Serial No. 602,725. (No model.)

The outer end of the sleeve-section c has a threaded connection with asleeve-head or end cap d, the latter being opposite the bearingring band having formed in its periphery a cone-bearing surface d.

d2 represent parallel rollers, the latter being arranged between thecasing-sections and sleeve-sections and having their exterior surfacestapering toward their outer ends to conform substantially to theinclines or tapers of said casin g sleeve-sections.

e represent bearing-balls, these balls being arranged in inner and outerrings and one of said balls bearing partially in each end of each of therollers and partiallyin the sleeve- .cap d, casing extensions b, andring c2.

j' represents a packing-ring, of felt or similar material, which isarranged in a recess formed partially in the end of the casing-ring band sleeve-ring c2. On the outer side of this packing-ring I provide afollower f.

g represents the outer end cap of the boxing, which, by means of screwsg', is united to said external boxing.

g2 represent set-screws which pass through threaded openings in the capg and have their inner ends in contact with the casing-ring b. This capis provided with a central adjusting and end-thrust-receiving screw h,the latter having formed in its inner end a threaded socket whichreceives a screw h. About the inner end portion of this screw isarranged a bearing-ring h2, and between said bearingring and the screw hI provide a cone-bearing block or ring h3. Between the ring h3 and ringh2 are interposed bearing-balls h4.

As shown in the drawings, the inner surface of the ring h2 is designedto be in contact with the outer end surface of the sleeve cap or headd..

i represents an axle-spindle which is surrounded by the sleeve-sectionsc and c and which is laterally movable therein.

In operation it is evident that the rotation of the axle-spindle willcarry with it the sleevesections c c', sleeve-cap section d, and innercone-bearing c2, while the external casing or box and its innercasing-sections a2 CL3 and cone-bearing ring b will remain stationary.It will be noted that the balls e are arranged partially in rings I) band partially against parts c2 d about the inner and outer sleeve- IOOsections, and that these balls are of such relative size with thecentral portions of the tubular rollers as to result, as indicated inFig. 3 of the drawings, in a comparatively light touch of the balls ofeach circle or ring. In this manner it is obvious that not only therollers but the balls themselves will loere-V tained at all times inparallel alinement with each other and that no frictional contact Willexist between the roller-bodies. It will thus be seen that the frictionbetween the bearing parts of my device will be exceedingly slight.

By employing a ball, as herein shown and described, at each end of eachof the. roller-l bodies it will be observed that each pair ofoppositely-located balls practically become a Part of the lollel,` rniebthey ndion.-

From the. construction which I hlaYe shown and described it isobyionsthat adjnstlnent of the balls or the partswithin which they bear for thepinpose of compensating for Wear on said balls or parts may beaccomplished by pro-per rotation of the ndinStng-senewn o? andend-tnrust-receiving screw In It Will bel observed tbet the pntsof myimproved journal-,boxare` few, Sllnpleof con.- strnction, and positivein operation, and that the Saule may be produced at a reasonable cost ofmannfactnre.

As indicated in Fig. d ofthe drawings., l may modify tl'ieyconstruction1 liereinbetoreA de: Senibed by the oonntrnetion of each of.the rollers in two separated sections, which are indiodted at 7e, end7e', and by the employment of4 a central or third ring; of balls 75,2,'which fne nlndneed between end hevether periph: i

in connection with said roller-sections additional means are providedfor retaining the i rollers in alinement.

, what l claim, and desire to secure by Letters Patent, is-
